Getting Started
NPM packages
ol-ext exists as ES6 modules (ol-ext) and as pure js (deprecated! openlayers-ext).
using ol-ext in a webpack
- For use with webpack, Rollup, Browserify, or other module bundlers, install the npm ol-ext package and link to the node_modules directory:
npm install ol-ext
OpenLayers is a peer dependencies, so you need to install it as well.
npm install ol
Then in your js file you can import the classes as follow:
1import "ol/ol.css" 2import "ol-ext/dist/ol-ext.css" 3 4import LayerSwitcher from "ol-ext/control/LayerSwitcher"
See the following examples for more detail on bundling ol-ext with your application:
Typescript declarations are avaliable at Siedlerchr/types-ol-ext.
npm i -D @types/ol-ext@npm:@siedlerchr/types-ol-ext
using ol-ext in a web page
- For use in a web page install the npm openlayers-ext package (deprecated):
npm install openlayers-ext
The library will be available in the node_modules/openlayers-ext/dist directory. You can find individual files in the node_modules/openlayers-ext/lib directory.
- You can download the scripts of the ./dist directory of the repository in your project and insert the .js and .css in your page.
- If you just want to add a
<script>tag to test things out, you can link directly to the builds from the github rawgit (not recommended in production). - For compatibility with older browsers and platforms (like Internet Explorer down to version 9 and Android 4.x), the OpenLayers needs to be transpiled (e.g. using Babel) and bundled with polyfills for
requestAnimationFrame,Element.prototype.classList,Object.assignandURL.
